What were major effects of the columbian exchange?

The Columbian Exchange significantly transformed global agriculture, economies, and populations by facilitating the transfer of crops, livestock, and diseases between the Old and New Worlds. Staple crops like potatoes, tomatoes, and maize were introduced to Europe, enhancing diets and boosting populations. Conversely, European diseases such as smallpox devastated Indigenous populations in the Americas. Additionally, the exchange led to the rise of the transatlantic slave trade, as labor was needed to cultivate cash crops in the New World.
